Abstract
Apparatuses, systems, and methods are presented for calibrating an inspection system, particularly a Laser Bond Inspection (LBI) system that identifies a strength of a test structure. The disclosed calibration system comprises a calibration panel, a surface motion sensor, and a processing circuit. The surface motion sensor senses a compression wave generated in the calibration panel responsive to a laser pulse applied by a LBI head to the calibration panel. The processing circuit outputs a calibration result for the laser inspection system responsive to one or more characteristics of the sensed compression wave. The calibration system provides significantly faster calibration results, and thus may be implemented more frequently to improve the accuracy and repeatability of the inspection system.
